问题描述

我想根据评论 ID 在 drupal 中打印单个评论.我怎样才能做到这一点?谷歌和其他来源没有给我任何结果.谢谢你.

I want to print a individual comment in drupal based on it's comment ID. How can I do this? Google and other sources have yielded me nothing. Thank you.

推荐答案

Eaton 的建议很好(除了它是 {comments}，而不是 {comment})如果你需要像 core 一样显示评论，包括来自节点的信息.除了 modules/comment/comment.tpl.php 中的默认 theme_comment 实现不使用 $node.

Eaton's suggestion is good (except it's {comments}, not {comment}) if you need to display the comment like core does it, including the info coming from the node. Except the default theme_comment implementation in modules/comment/comment.tpl.php makes no use of $node.

但是，我的做法略有不同，因为如果您需要提取单个评论，以comment.tpl.php 提供的正常内容格式显示它可能是不合适的.

However, I'd do it slightly differently, because if you need to extract a single comment, displaying it with the normal content formatting provided by comment.tpl.php is likely to be inappropriate.

function print_comment($cid) {
  $sql = "SELECT * FROM {comment} c WHERE c.cid = %d";
  if ($comment = db_fetch_object(db_rewrite_sql(db_query($sql, $cid), 'c'))) {
    return theme('my_special_comment_formatting', $comment);
  }
}

当然，受 comment.tpl.php 的启发，在模块的 hook_theme() 实现中定义这种特殊的注释格式.

And of course, define this special commment formatting in your module's hook_theme() implementation, inspired by what comment.tpl.php does.

2014-02 更新:请注意，这是 2009 年的问题/答案.在 Drupal 8 中，您只是不想访问假设的底层 SQL 数据库(无论如何都不会这样做，而是使用 DBTNG)，而只是使用类似的东西:

2014-02 UPDATE: note that this is a 2009 question/answer. In Drupal 8, you just don't want to access the hypothetical underlying SQL database (and would not do it like this anyway, but use DBTNG), but just use something like:

if ($comment = entity_load('comment', $cid)) {
  return entity_view($comment, $view_mode);
}
